UNITED STATES PATENT OFFICE GEORGE H. RUGG, OF MINNEAPOLIS, MINNESO'IA.

IMPROVEMENT IN LUBRlCATlNG-AXLES FOR VEHICLES.

Specifica.tion forming part of Letters Patent N0. 158,003, datedDecember 22, 1874; application filed November 19, 1874.

T0 all whom z't mag] ooncem:

Be it known that I, GEO. H. RUGG, a resident 0f the city 0f Minneapolis,county of Hennepin and State 0f Minuesota, have invented a new anduseful Improvement in Webicle-Axles, 0f which the following is a. full,clear, 21-nd ex act descripnion, reference being had to the accompanyingdrawings, being made apart 0f this specification, in which- Figure l isa cross-section. Fig. 2 is a, top view 0f axle. Fig. 3 is a. prspectiveview of Ehe fillet.

lhe objec 0f rny invention is to enable any person having a vehicle t00il the wheels and axles thereof without removing the wheels.

T0 enable others skilled in the art to make and use my invention, I Willproceed 130 describe the preeise manner in which I have 02mried it 0ut.

I take the cast-iron skein, wrought-iron or steel axle A, and form inits upper side a groove, B, whose Width is in proportion 130 t-he sizeof the axle. In the formatiou of this groove I make its base wider thanits top, thereby giving its sides a beveled form, tl1at they may retaiuthe 011 01 grease cup O. Fit;- ting into the 011 01 grease cup O is thefillet; E, which, when in position, completes the round of the ax1e. T0enable tl1e operator 150 readily pul1 out the 0i1 or grease cup (J one0r two lugs, D D, are attached t0 its 0uter end, rhe notch F beingformed in the outer eud 0f the fillet E for the same purpose. The

groove in the ax1e may exten tl1e length of the hub 0r less, as may bedesired, the fillet E, together With the 0i1 or grease cup O, completelyfilling up the groove.

In using my inven1aion the nut is taken oft from the outer end of theaxle, am]. the fillet E, together with the oil-box O, is withdrawn from11110 groove therein. The fillet E having been removed from t-l1eoil-box C, said box is filled with the lubricating material and replacedin the groove B. The fillet E is theu replaced, forcing ehe oil out ofthe box G und into the hab 0f the wahicle and around the axle. The nutis theu replaced and the szune operations gone through with the otherwheels.

I am aware that axles 0f vehicles hzwe been grooved and plugs used f0rpressing back the lubrieant; but this is not my invention.

Having thus described my iuvention, what I claim as new, and wish t0secure by Letters Patent, is

l. The oil-box O, with its fillet E, 120 0pemte within a groove in thespindle 01 skein of a vehiele-axle, substantially as and f01 thepurposes specified.

2. A spindle 01 skein of a vehicle-axle, having a groove, in combinationWith an oil-cup aud fillet, substantially as and for the purposesspecified.
